HLT-1110 Series
HITROL CO., LTD. 3
The HLT-1110 Series level gauge is an instrument used to measure the level of fluid stored in the tank
using a spring as the float moves. It can be used in a variety of industries such as crude oil, oil refining,
petrochemicals, food industries, power plants, and water treatment.
It consists of a measuring tape and a gauge head connected to the float. The float floats on the liquid
surface in the tank as sinking until the point where the weight of the float and the buoyancy of the
float are balanced. When the float is submerged, it is balanced by its own buoyancy and tension on
the measuring tape. The measuring tape is wound to a tape drum located inside the tank gauge head
and transmits tension to a spring drum. This instrument uses a spring to measure the level of fluid
stored in the tank as the float moves.
